Hey Patrick,
Nice work on both machines. I am looking for a T75 and yours looks great!
Your T23 looks way nicer than mine.

You are right around the upper rpm limit for rubber sealed bearings. It may be a good idea to buy shielded ones instead. You need to do some homework about that. Having pumped oil supplied to the bearings causes me to wonder about the type that should be used even more. Bearings have improved in th last 50 years and what was done at the factory in the day may not be the best choice with todays lubes and bearing materials.

If you have questions feel free to ask. I have received so much help from so many. I’m not afraid to ask for help and I find most of the time people that “know” share the same passion as I do and are happy to pass it on.
I’ll start by sharing pictures of your quill and spindle. It’s pretty straight forward but kinda no small task as you have to drop the motor to do it. The motor has a mount that is bolted to the bottom of the quill.

With the motor off you gotta take off the pulley.

With the pulley off you gotta get the spindle apart. It’s highly sequential. Beware there is one spacer that looks pressed on but is actually threaded...

You might as well do the motor bearings. They are basic 603C or something. I have a extra full set in my toolbox for both the motor and spindle. The motor bearings were exactly the same as in my T75 so I bet they are the same in your machine. But hot dam the spindle bearings are a whole nother ballgame. I would hope I you know at this point they are a oil drip system. That’s what the pump is about. These bearings are a phenolic or basalite open cage. The oil to be used with them is very specific per Martin and resides in Germany and can only be shipped via a freighter. So it takes weeks to get it. I did tons of research on the bearings and founds that mobile Velocite 6 is the the answer. It’s what I have been running and it’s working great. Best sit down as the whole lot of bearings motor and spindle were like $700. I was silly and purchased four of each in the event anything went wrong or I need them again. The spindle bearings are not so easy to find. Accurate did not have them but was able to get them for me.
Martin sells a greased bearing so called upgrade kit “$7k” and three weeks out minimum.
Now beware and you had better hope to hell your oil pump works. If not that’s a whole nother can of worms. I won’t get into it here unless you need me to. Cost me about $1200 and couple moths of head scratching with a friend driving various pump manufactures And electronic widgets nuts.
If the pump is gone you may need some divine inspiration.
And my suggestion would this be to..

Good luck and remember to have fun. Do it right and you will have no regrets. With the motor and quill dropped it would had been pretty easy to do a full resto in many 40 hrs. But I was in my home shop with no place to sand out 3000 coats of bondo and or shoot autobody paint.
Yes it is lol.. it had a huge crack the length of the bottom. Started with JB weld and that would had been fine but I couldn’t just leave it like that.

Thanks Dave, it was both pretty easy and a total bitch.
I’m not totally happy but I gave up. And as most know It’s pretty hard to get me to quit.
I have since done tons of research. Next time I’ll nail it. And next time will probably be when I restore this machine or take home a t23 tenon table I’m waiting to be able to afford.
Patrick.... in pursuit of absolute!
bit of overkill Mark for the Saturn, maybe the 72 pickup though
Life is about venturing out of the cave and seeing what's out there, how far you can go, what lies beyond.
Warren, i think they would look good on the 72 pickup.
Patrick, keep on being you... you do it better than anyone i know.
